Thick-walled wound fibrous-composite structures

Abstract

Recent research on the high compliance of the modern fibrous composites in the transverse direction is reviewed. The following topics are examined in detail: deviations from the elastic-ring winding model, the effect of initial imperfections, methods of studying and taking into account the physical nonlinearity of the radial stress-strain dependence for thick-walled, essentially anisotropic rings operating under pressure, allowance for the compressibility of the normal in bending of bars with a circular axis made of high-modulus materials, and the effectiveness of the radial reinforcement of wound structures. It is shown that the high compliance of the semifinished product and finished articles in the transverse direction, the effects it produces and methods of eliminating them are one of the central problems in designing thick-walled wound structures.
